Fadnavis drove to Raj Bhavan in south Mumbai and submitted his resignation to Governor Bhagat Singh Koshyari, sources said.

There has been no headway in government formation even a fortnight after Assembly poll results were announced on October 24.

The BJP and Shiv Sena are locked in a tussle over the issue of the chief minister's post, resulting in a stalemate in government formation despite the Assembly poll results giving the alliance a combined seat strength of 161, way past the 145 majority mark in the 288-member House.

In the polls, the BJP won 105 seats, Shiv Sena-56, NCP-54 and the Congress won 44 seats.
